Abstract: A refresh rate switching method and an electronic device are provided. In the method, the electronic device dynamically switches a corresponding screen refresh rate by determining whether a current display image is a high frame rate scenario or a standard frame rate scenario. In the high frame rate scenario, a relatively high screen refresh rate is used to support a high display frame rate. In this way, a user can obtain experience of the high display frame rate, and the display image is smooth without motion blur. In the standard frame rate scenario, a default low screen refresh rate is used to reduce power consumption of an entire system.
